test/blobfs: Allocate enough memory for db_bench tests

Browse Source 
Currently, BlobFS-nightly-autotest jobs are failing due to this test
not having enough memory around. Change that by allocating some
overhead depending on what CACHE_SIZE was set to.

# Make sure that there's enough memory available for the mempool. Unfortunately,
# db_bench doesn't seem to allocate memory from all numa nodes since all of it
# comes exclusively from node0. With that in mind, try to allocate CACHE_SIZE
# + some_overhead (1G) of pages but only on node0 to make sure that we end up
# with the right amount not allowing setup.sh to split it by using the global
# nr_hugepages setting. Instead of bypassing it completely, we use it to also
# get the right size of hugepages.
